GRCA maintains a collection of data layers for its Geographic Information System (GIS). You can
download over 50 layers of data directly from our data catalogue.

We constantly monitor stream flow, water quality, meteorological conditions, and
operational conditions at GRCA dams. This information is collected and transmitted from each station to
GRCA's Operations Centre in Cambridge, Ontario once an hour.

This is where the downloadable items that don't have a home elsewhere all live. Large scale PDF maps of the watershed,
Groundwater models, and other items can be found here.
